435 FNUS55 KPSR 191102 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 402 AM MST Sun Jan 19 2025 .DISCUSSION... Temperatures should hover close to the seasonal normal through the middle of next week with expansive dry air in place resulting in essentially no chance of wetting rainfall. Minimum afternoon humidity levels will settle in a 15-25% range today, then closer to a 5-15% range next week with a renewed surge of drier air. Weekend fair to good overnight recovery of 30-60% will deteriorate towards poor recovery of only 15-30% next week. While some gusty north winds resulting in a period of elevated fire danger will exist mainly on Monday and Monday night for the western districts and some higher terrain areas of the eastern districts, light winds will become more common over the remainder of the region. Note...Additional Fire Weather Forecast information can be found in the Area Forecast Discussion. See product PHXAFDPSR.
